MUD-GUARD Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed April 28, 1908. Serial No. 429,688.

To all whom it may concern:

Be it known that I, WILLIAM D. SNOW- MAN, a citizen of the UnitedStates, residing at Ashland, in the county of Aroostook and State ofMaine, have invented certain new and useful Improvements in Mud-Guards,of which the following is a specification.

This invention relates to farming implements, and more particularly tothose having gears rotated by chain connections, and has for its objectto provide a suitable means for protecting such connections from damageby engagement therein of stones, dirt, or other injurious material.

A particular object of the invention is the provision of such an articlewhich is detachable, and adapted to engagement with various types ofmachinery.

Another object is the creation of a simple structure of this type whichmay be manufactured at low cost from stock material.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimsand that any suitable materials may be used without departing from thespirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a side view of the guard, Fig. 2 is a cross sectional view,Fig. 3 is a top view of the device, Fig. 4 is a side view of a modifiedform of the device.

Referring to the drawings, there is shown a casing 10 of sheet metalcomprising spaced side portions 11, a top portion 12 connected with andextending therebetween, and an end portion 13. It will be understoodthat the casing may be made of various shapes for the purpose ofinclosing revoluble gears, moving chains, reciprocating parts, andvarious other mechanisms required to be inclosed.

Secured to the outer sides of the wall 11 there are outwardly extendingsupporting portions 15 which may be made of malleable metal, or maycomprise adjustable sections of nonmalleable material if desired. Asshown, the members 15 comprise rods of iron yoke shape, one end beingriveted to the walls 11 and the other end being bifurcated and providedwith registering threaded openings 9 in the bifurcated extensions 16,adapted to receive threaded bolts 17 therethrough. The space 18 betweenthe bifurcated portions is adapted to receive therein portions of stayrods or supporting frame-work adjacent to the parts over which thecasing is to be adjusted. The bolt 17 may then be rotated to impingeagainst such portions engaged in the space 18 to retain the case inposition, or engaged in the adjacent registering opening 9 to bind anengaged part between the portions 16. It will be understood that thesupport members 15 may be made of any shape desired, and in order todispose the casing in proper position, it will be understood that anysuitable securing means may be used in place of the bifurcated portion16 and the bolts 17 As shown in Fig. 5, the securing means comprise alaterally extending offset U shaped portion 20 secured to the end of themember 15, and adapted for engagement with supporting portions in amanner similar to that above described.

A particular object of this invention is to provide such a deviceespecially adapted to use with potato diggers.

What is claimed is 1. As an article of manufacture, a mud guard for usein connection with potato diggers comprising an arcuate portion formedfrom sheet metal and including parallel sides and a connecting top, andsupporting members secured to the outer face of one side portion of saidarcuate member, said supporting members extending in parallel verticalplanes, and having downwardly directed yokes at their ends distant fromthe arcuate member, said yokes being adapted for engagement withportions of a potato digger to support the mud guard, and set screwsengaged in the yokes.

2. A mud guard for potato diggers comprising a shield stamped from sheetmetal and including a longitudinally curved top and depending verticalsides carried by the edges of the top and lying in spaced parallelrelation and supporting members secured to the outer face of one of saidsides, each of said supporting members being secured to the side at oneend and being curved upwardly and outwardly and then downwardly andhaving a yoke at the extremity of its downwardly curved portion, saidsupporting members extending in parallel vertical planes and projectingabove the top of the shield at the end thereof.

In testimony whereof I affix my signature, in presence of two witnesses.I

WILLIAM D. SNOWMAN.
